Claims.

This invention-relates to a brush wherein the bristles are retractablewhen not in use.

An object ofl my invention is to provide a novel brush wherein'` thegroups of bristles are indel5 pendently mounted. The mounting means forthe bristles being engaged for the purpose of extending and--distendingthe bristles when the brush is in use, and disengaging the mountingmeans so thatlthe bristles can be compacted when the brush is inl foldedposition. l

Another obliect' is to provide a novel actuating cover mountedn thebrush case, said cover actuating the bristles for the purpose ofextending or retracting thesame.

Still another object is to provide a novel brush of the character statedin which a hingedly mounted coverjactuates a plunger, said plunger inturn engaging the base of the bristles for the purpose of distendlngsaid bristles when the bris- 00 tles are extended from the case anddisengaging the base of the` bristles so that said bristles arecompacted when said bristles are retracted.

A further object is to provide a brush of the character stated which iseiective in operation.

Other objects advantages and features of invention may appear from theaccompanying drawing, the jsubjoined detailed description and theappendedgclaims.

. Figure 11 is a fragmentary vertical sectional view of one of thebristles.

Figure 12 is a. fragmentary transverse sectional view of the brushshowing a comb extending into thebristles.

Referring more particularly to the drawing,

the numeral I indicates an outside case which is open at the top, asshown at 2.

A cover 3 is mounted on the case I and the purpose of this cover will befurther described.

The cover 3 is substantially U-shaped and is hingedly and sldablymounted on the case I, as will be further described.

A tray 4 is sldably mounted in the case I and this tray carries aplurality of bristles 5. The bristles are mounted in a row and in a base6. The bases 6 are substantially wedge shaped and a plurality of thesebases are arranged side by side substantially as shown in Figures 7 and10. The bases 6 are retained in the upper part of the tray 4 and thesebases are tiltable for the purpose of distending the bristles, as shownin Figures 2 and 3. The bases 6 rock through a slight angle from thedistending position shown in Figure '7 to the contracted position shownin Figure 10. The bases 6 are engaged and rocked in the tray 4 for thepurpose of distending the bristles by a plunger.

This plunger is sldably mounted in the tray 4 and is moved vertically bythe swingingcover 3 through suitable means such as the eccentric shaft8.

The outer ends of the shaft are xedly mounted in the cover 3 while thecentral eccentric portion of the shaft extends through an elongated slot9 in the plunger 1.

It will be evident that when the cover 3 is moved from the positionshown in Figure 2 to that shown in Figure 4, the shaft 8 will be rotatedthrough 180 degrees and will thereby move the plunger 'l from theposition shown in Figure 7 to that shown in Figure 10.

A tapered recess I0 is provided in the upper face of the plunger 1 andthe tapered walls of this recess engage the wedge shaped bases 6 for thepurpose of distending the bristles when the plunger is forced upwardlyto the position shown in Figure 7.

'I'he case I is provided with a vertical slot II in each end thereof andthe shaft 8 is slidable in these grooves thus permitting the cover 3 toslide downwardly thereby forcing the tray 4 downwardly for the purposeof retracting the bristles 5.

Before the cover 3 can move the tray and the bristles downwardly it mustbe swung into the position shown in Figure 4. Thereafter it can bepushed downwardly covering the opening 2 and simultaneously retractingthe bristles.

At the time the cover 3 is swung upwardly to the position shown inFigure 4, the plunger I will be moved downwardly as shown in Figure l0.'I'he bases 6 of the bristles are then free to rock inwardly permittingthe bristles to be compressed.

The bases 6 preferably engage the adjacent bases and rock against eachother about the rounded upper surfaces thus insuring that no foreignmaterial will drop down through the bristles and between the bases toprevent their being wedged outwardly as shown in Figure '7.

If desired the cover 3 may be provided with an elongated slot in theclosed end thereof through which a comb l2 can be inserted. The combextends into the bristles 5 when said bristles are in retractedposition, and the bristles will serve to hold the comb in the cover.

Having described my invention, I claim:

1. A retractable brush comprising an outside case, a plurality of brushbases slidably and pivotally positioned within the case, tufts ofbristles mounted in each of the bases, means slidably mounted in thecase, said meansv being engageable with the bases and moving them toextended position, said means being adapted to extend or retract thetuft from the case, said bases being substantially wedge-shaped in crosssection, a second means including a wedge-shaped socket engaging thebases when the tufts are extended, thereby distending the tufts, saidlast named means disengaging the bases when the bases are retracted.

2. A retractable brush comprising an outside case, a plurality of basesslidably and pivotally mounted in the case, tufts of bristles in each ofthe bases, a cover reversibly mounted on the case, means operablyconnected to the cover and engageable with the bases, whereby said basesare moved vertically in the case to extend or retract the tufts, saidbases being substantially wedgeshaped`in cross section and meansincluding a wedge-shaped socket operably connect-ed to the cover andoperable on rotation of the cover relative to the case, thereby engagingthe bases when said bases are moved vertically and thereby distendingthe tufts projecting from the case.

3. A retractable brush comprising an outside case, a tray slidablymounted in the case, a plurality of bases mounted in the tray, bristlesprojecting from each of the bases, a cover reversibly and slidablymounted on the case to cover either end of the case, means operablyconnecting the tray and the cover whereby said tray is moved in the caseby said cover, thereby extending or re-g tractingthe bristles, means inthe tray adapted to engage the bases whenlextendedand xedly hold saidbases against movemenhw'a means operably connecting saidlastvflamed'm'eans and the cover, whereby movement of the cover will engagethe second named means with the bases.

4. A retractable brush comprising an outer case, a tray slidably mountedin the case, a plurality of pivoted and extensible bases mounted in thetray, a cover, ari-.eccentric shaft, attached to the cover and extendinginto said tray, a means in the tray and engageable by said shaft, said20 means engaging vthe bases and moving them to extended position, saidmeans having cam faces whereby the bases are vrocked about ltheir pivotsto distend the bristles, said means comprising a plunger.- f p k 5. Aretractable brush comprising an -Vouter case, a tray, slidably mountedin the casc,.acover pivoted and mounted to said caseby an eccentricshaft attached to the coverv and extending into the tray, said casehavin-g slotsinthe side thereof through which said shaft extends, aplurality of bases mounted in the tray, bristles extending from thebases, said bases being rockable in the tray, a plunger in the tray,said shaft extending into the plunger wherebyv the lplunger is movedvertically as the cover is rotated, -said plunger having a Wedge shapedrecess thereim said v-recess engaging the bases lwherebysaiclbasesare-rocked to distend the bristles.
